ADJUSTABLE BOOK-REST.

Specification of Letters Patent.

Patented March 23, 1909.

Application filed May 12, 1908. SerialNo. 432,348.

To all whom it may concern:

Be it known that I, LELAND VALENTINE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Book-Rests, of which the following is a specification.

My invention relates to devices designed to support books, newspapers, etc., in position W ere they may be easily read, the object being to provide a book rest which may be easily ad uSted for angular direction, wherein the book so supported may be tilted at any angle desired and there held, and wherein the book rest may be attached either to a suitablebase or clamped upon a table, chair or other article of furniture.

Figure 1, is a perspective view of the'book rest. Fig. 2, is a side View. Fig. 3, an enlarged detail, the standard being partly broken away at its lower end. ,Fig. 4, is a View showing an adjustable'extension arm and clamp, the end ofsaid arm'being in section to show the attachment'thereof to the clamp. Fig. 5, is a sectional detail enlarged of the clamp used on the bracket, the sec tion being taken on line 5, 5, of Fig. 4.

Like characters designate like parts in all of the several views. Referring to Figs. 1, 2 and 3, 2 designates a base, having legs 2, the center of the base being provided with an upwardly'projecting pillar 3, which is reduced at its upperend so that a shoulder 3 maybe formed; The standard 4, is tubular and has attached to its upper end a U-shape yoke 5, the upper ends of which carry av pivot pin 6, upon which the book rack proper is pivotally mounted. The book carrying rack 7, is formed of one piece of wire, the rack being pivotally supported at its middle on the pin 6. The up er portion 7, of the rack is formed by ending the wire in an ap roximately triangular shape, the apex of t e triangle being downward. Where the side wires of this triangle near each'other, the wires are coiled a number of times about the pin 6, as at 7, to form the pivotal bearing of the frame. The ends of the wires are then bent outward in opposite directions from each other to a width about equal to that of a book when open, then bent downwardly as at 7 then outward at right angles, to form the bottom of the rack on which thebook is supported. The two:ends:of the .11, and a clamp br'ac signedto be 'used in place of the'base 2, when movement downward, though a wire are then bent toward the middle of the front of the rack as at 7. Here the ends of the wire meet and are twisted together as at 8, and bent inward toward the standard.

One of the ends of the wires, 8, is extended upward at the same angle as the side book sup orts 7, and forms a support for the.

bac of a book. The other end 8 of the wire, passes loosely through an opening in the standard 4, and extends rearward in the arc of a circle. The set screw 9, operates through the side of the tubular standard and binds against the end 8", this portion of the wire, thus forming an'adjusting bar whereby the rack may be set, andheld at any angle desired. i

In Fig. 4, Ishow a ivoted extension arm ket 12, which are dethe book rest is to be attached to some article of furniture, as for instance a' chair or bed. The clamp bracket 12, has at one end the clamp screw 12, and the up er and lower plates of said bracket are per orated for the passage of a'rot'atableshaft '13, having a pilar 13, on its u perend. This shaft has also a vertically sli' ing movement in the bracket.

Between the upper and lower plates is the strengthening web 14, having a rib 14, the

upper end of this rib is laterally extended on both sides as at 14", forming a support or socket for the inner end of a clamping plate 15'. The inner end of the clamping plate is see Fig. 5, to fit over the bifurcated as at 15, rib above the lateral extension thereto 14". The plate has an opening 15", through it for the passage of the shaft 13. This opening is slightly larger than the shaft so that when the plate 15, is at right angles, the shaft passes through easily, but when slightly inclined from the horizontal, the plate will jam and bind on the shaft preventing its further owing it to be raised any extent desired. end of the shaft has a shoulder as at 13 to form a bearing flange at the base of the pillar 13. It will be noticed that the tubular lower end ofthe standard 4, fits over'thepillar3of the base and may liedetached therefrom. This lower end of the standard also fits on and over the pillar formed on the upper end of the shaft 13, so that the book vest may be supported directly upon the shaft 13, if desired. If however, it is necessary that the book should be held at some distance awayifrom thel'supporting base, I provide The u per.

one or more extension arms 11. These'arms I screw engaging and holding the adjusting are each provided at one end with a socket 1 6, adapted to fit over the upper end of the shaft 13, and against the shoulder 13. At the other end, the arms each have an upwardly extending pillar 16, of the same diameter as the pillar 3, which is adapted to be inserted into the socket 16, of another extension arm of like character, or into the open end of the standard 4. The illar 16, is likewise provided with a shoulder 16", at its base. There may be as many of these arms 11, as desired, though I have only shown one, and by using them the book may be carried at any position upon the frame of a chair or other support.v It will be noticed that the extension arms are easily attached or detached and that by reason of the shoulders 13", or'16, the arms have a very strong bearing upon the pillar 13, or upon each other.

My invention provides a book rack easily adjustable as to inclination or angle of rotation and one wherein the ordinary base for table use is interchangeable with pivoted arms adapted to be clamped to a chair, bed or other support.

While I have referred to my device as particularly designed for the support of books, I of course do not wish to be limited thereto as it may be used for analogous purposes.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is 1. A holder for books or other articles having a vertical rotatable standard, a horizontal pivot pin carried on the u )per end of the standard, and a book rack of wire, coiled at its middle around said pivot pin to form a bearing for the rack, the rack being exp and ed laterally above and below said pin.v

2. A holder for books or other articles having a vertical rotatable standard, a horizon tal pivot pin carried on the upper end of the standard and a book rack of wire pivoted thereon, said rack being made of one piece of wire formed into an approximately triangular shape, then wound about said pivot pin toform a bearing for said rack, the two ends of the wire then extended laterally, then bent downwardly, outwardly and toward each other meeting at the middle of the front of the rack, said ends of wire being there intertwined with each other for a distance and bent inwardly toward the standard, one of said ends then passing through an opening in the standard to form an adjusting rod, the other being turned upward to form a back for the said rack, said standard having a set rod set in any position.

3. A holder for books or other articles having a tubular standard carrying a book rack at its upper end, the lower end of said standard being open to form a socket; in combination with a bracket clamp having projecting ears, an upwardly projecting rod vertically movable through said ears provided at its upper end with a pillar on which the open end. of the rack standard is adapted to lit, a clamping plate through which said upwardly projecting rod loosely passes, means on the bracket [or holding one end of said plate loosely engaged and preventing sidewise movement ol the engaged end ol the plate and an arm one end of which is provided with a socket adapted to "lit over the pillar carried by the vertically movable rod, the other end of which has an upwardly projecting pillar on which the open end ol the rack staiulard is also adapted to 'lit.

4. A holder [or books or other articles having a tubular standard carrying a book rack at its upper end, the lower end ol' said standard being open; in combination with a bracket clamp having upper and lower plates connected by a rib, said rib having lateral extensions near its upper end; a rod passing through said bracket clamp; clamping plate loosely mounted on said rod, one end of the plate being bifurcated to engage the rib on said connecting web, the upper end of the rod being extended to form. a pillar; and an arm having a socket at one end to fit over said pillar and at the other end an upwardly 'nojecting pillar adapted to project into and engage with the open lower end of said standard.

5. A holder for books or other articles having a standard carrying a book rest at its upper end, the lower end oi said standard being open; in combination with a bracket adapted to be clamped to a piece of furniture and having projecting cars, a vertically sliding smooth rod passing through said ears, a plate through which said rod loosely passes located between said ears and means for loosely engaging one end of the plate with the bracket and preventing sidewise movement of the engaged end of the plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses LELAND VALENTINE.
